EasySC: a supply chain integrated modeling and simulation software

The existing simulation software suites are hard to understand when applied to supply chain business. So an integrated modeling and simulation environment based on discrete-event method is proposed in this paper, as well as the supply chain model used in this software framework. The whole supply chain is consisted of enterprise nodes and links. Each node is made from supply, deliver, make, transportation, inventory, and finance, and links can represent transportation route, supply and demand relationship, or service relationship. The operations of supply chain are derived by the supply and demand relationships between enterprise nodes.
